Description 

The following bug report has been submitted:
Platform:        Linux-3.10.0-957.12.2.el7.x86_64-x86_64-with-centos-7.6.1810-Core
ChimeraX Version: 0.91 (2019-06-25)
Description
Seems to have lost some tab-completion functionality in the shell:

import numpy
numpy.<tab><tab> # does nothing (should list available methods)
numpy.linal<tab> # does nothing (should auto-complete to linalg)
numpy.linalg.nor<tab> # does nothing (should auto-complete to norm)

from matplotlib import pyplot as plt
plt.<tab><tab> # Does nothing (but did seem to hang for a second or two the first time)
plt.sca<tab> # Successfully autocompletes to scatter

from chimerax import atomic
atomic.<tab><tab> # Works as expected

Summary: ChimeraX bug report submission → Erratic shell tab completion

Jupyter apparently uses something far fancier that simply looking at dir(module) for tab completion, and gets confused by complex modules like numpy and matplotlib. There is some discussion here: ​https://github.com/davidhalter/jedi/issues/372 . Seems like all we can do is hope that future releases of ipython improve the behavior.
